Eric Bergen from Proven Scaling (which I had the pleasure to meet in person during the MySQL Conference & Expo in Santa Clara last month) was kind enough to send me a patch for the mylmbackup tool, which justifies a new release:

Attached is a patch file for mylvmbackup that adds the ability to use
lvm version 2 and perform innodb recovery on the snapshot prior to
creating a tar ball. The option is named --innodb-recover.

I've also fixed a bug with default value handling for command line
options. In version 0.4 if a config file was specified default values
in the script were all changed to blank. This means that the config
file had to supply values for every variable instead of just the
values that need to be changed from default.

This is a very useful addition, as it significantly reduces the time required to recover a MySQL server from a snapshot backup. Thank you, Eric! Note that you need to use LVM2, as LVM1 does not support the required writing to snapshot volumes.

Version 0.5 is now available for download from the mylvmbackup project page.

I also would like to announce that I have set up a dedicated mailing list for this tool: if you want to discuss the usage/future of mylvmbackup, propose patches or ask for help, there now is a mailinglist, hosted on FreeLists.org. To subscribe, either enter your email address on the mylvmbackup list information page or send an email with the subject "subscribe" to mylvmbackup-request@freelists.org. The list is archived here. See you there!
